RESUMO

The presence of mammographically evident hyperdense foci within axillary lymph nodes elicits concern for calcium deposits, which in turn have a wide differential diagnosis including both benign and malignant entities. Tissue sampling, most commonly by way of image-guided core needle biopsy, is needed in many cases when a definite etiology cannot be clinically established. In this case series we present history, imaging findings, and pathology results (or long term follow-up stability as biopsy surrogate) of several women with body tattoos who at mammography were noted to have a characteristic pattern of "bubbly" pseudo-calcifications within axillary lymph nodes, and absence of other mammographic, sonographic and clinical abnormalities.

RESUMO

BACKGROUND: Annular and left ventricular outflow tract (LVOT) calcification increase the risk of annular rupture following transcatheter aortic valve replacement (TAVR). The outcomes of a strategy of routine use of a balloon-expandable valve (BEV) for all patients irrespective of annular or LVOT calcium is unknown. OBJECTIVES: We evaluated the impact of bespoke sizing on annular rupture in patients treated with a BEV. METHODS: All consecutive patients undergoing TAVR at a single centre (February 2020-February 2022) were treated only with a BEV. No other valve design was used. Annular/LVOT calcification was assessed using a standardized grading system. For each annular area, we determined the percentage valve oversizing with nominal deployment. The balloon deployment volume was then adjusted when required (over-/underfilled) to achieve over-sizing of approximately 5% in the presence of annular/LVOT calcium and 5%-10% in the absence of annular/LVOT calcium. Adjusted valve areas were assumed to change proportionately to the change in balloon deployment volume. RESULTS: Among 533 TAVR treated patients, annular/LVOT calcification was present in 166 (31.1%) and moderate or severe in 90 (16.9%). In patients with annular/LVOT calcification, the adjusted oversizing was 3.5 ± 3.6% and in patients without annular/LVOT calcification, the adjusted oversizing was 6.8 ± 4.7% (p < 0.001). There were no cases of annular rupture and no cases with more than mild paravalvular leak (PVL). Mild PVL was more frequent in patients with annular/LVOT calcium (10.8% vs 4.6%, p = 0.01). CONCLUSION: Bespoke BEV sizing by adjustment of balloon deployment volume avoided annular rupture in patients undergoing TAVR.

RESUMO

A calcified amorphous tumor( CAT) is a non-neoplastic cardiac tumor, which has been reported to be associated with hemodialysis dependent end-stage renal disease. We report a case of CAT attached to mitral annular calcification (MAC) in the posterior leaflet annulus of the mitral valve in a 56-year-old man who had been receiving peritoneal dialysis for three years. The CAT grew to 10 mm long in a half year. Peritoneal dialysis dependent end-stage renal disease is associated with MAC. Additionally, MAC-related CAT has been reported growing rapidly. We should perform periodic echocardiography not only for hemodialysis patients but also for peritoneal dialysis patients. When CAT is diagnosed, operation should be performed early to prevent embolism such as cerebral infarction.

RESUMO

OBJECTIVE: to investigate the clinical characteristics of systemic lupus erythematosus with diffuse intracranial calcification. METHODS: The clinical characteristics of one case of systemic lupus erythematosus with diffuse intracranial calcification were analyzed, and 12 cases in related literatures were reviewed by searching Medline and Wanfang database. RESULTS: Our case and 12 cases reviewed were all female. With the exception of one case, the course of SLE was more than 5 years. The clinical manifestations of the nervous system are diverse, including epilepsy, hemiplegia, cognitive impairment, and mental abnormalities. In the presence of neuropsychiatric manifestations, this case and six cases reviewed had SLE activity. Cerebrospinal fluid (CSF) examination was performed in seven patients, including four patients with CSF protein elevation, two patients with IL-6 elevation, and one patient with anti-ribosomal p antibody elevation. This case and 10 of 12 cases reviewed had bilateral basal ganglia calcification. Intracranial calcification was very high density on CT and showed high T1WI and low T2WI signal on MRI. CONCLUSION: Systemic lupus erythematosus with intracranial calcification is a rare and severe manifestation of SLE, which is not completely parallel to SLE activity. The clinical manifestations of the nervous system are diverse, and bilateral basal ganglia calcification is the most common in imaging. High T1WI signal and low T2WI signal may be used as one of the imaging features to identify intracranial calcification.

RESUMO

PURPOSE OF REVIEW: The aim of this study was to provide updated information on the prevalence, pathogenesis, diagnostics and therapeutics of calcinosis cutis associated with systemic sclerosis (SSc). RECENT FINDINGS: Observational studies show ethnic and geographical differences in the prevalence of calcinosis. In addition to clinical and serological associations, biochemical studies and in-vivo models have attempted to explain theories behind its pathogenesis, including prolonged state of inflammation, mechanical stress, hypoxia and dysregulation in bone and phosphate metabolism. Long-term use of proton pump inhibitors may increase the risk for calcinosis in SSc. Few single-centre observational studies have shown mild benefit with minocycline and topical sodium thiosulfate. SUMMARY: Calcinosis cutis is the deposition of insoluble calcium in the skin and subcutaneous tissues. It affects up to 40% of SSc patients and causes significant morbidity. Long disease duration, features of vascular dysfunction and osteoporosis have been associated with calcinosis. Altered levels of inorganic pyrophosphate and fibroblast growth factor-23 have been implicated in dysregulated phosphate metabolism that may lead to calcinosis in SSc. Plain radiography can help with diagnosis and quantifying the calcinosis burden. Surgical treatment remains the most effective therapy when feasible. At present, no medical therapies have proven efficacy in large randomized controlled trials.

RESUMO

OBJECTIVE: To investigate the correlation between annular plaque calcification in the carotid sinus and perioperative hemodynamic disorder (HD) in carotid angioplasty and stenting (CAS). METHODS: The clinical data of 49 patients undergoing CAS due to narrowing of the carotid sinus were retrospectively analyzed. All patients had preoperative carotid computed tomography angiography (CTA) and were divided into HD and non-HD groups based on the occurrence of HD in the perioperative period of CAS. HD was defined as persistent bradycardia (heart rate < 60 beats per min) or persistent hypotension (systolic blood pressure < 90 mmHg) in the perioperative period and lasting for at least 1 h. The baseline data, including the degree of carotid artery stenosis, plaque length, plaque thickness, calcified plaque morphologies (i.e., plaque circumferential angle: < 90° defined as dotted calcification; 90°-180° defined as arcuate calcification; > 180° defined as annular calcification), contralateral carotid artery conditions, balloon diameter, and stent types, were compared between the two groups. Binary logistic regression was used to analyze the risk factors for the occurrence of HD. RESULTS: Among the 49 patients undergoing CAS, 14 (28.57%) developed perioperative HD, and 35 did not. Annular calcification was more common in the patients in the HD group than in the non-HD group. No significant differences in the probabilities of dotted and arcuate calcifications were found between the two groups (p > 0.05). The duration of continuous dopamine consumption in the HD group was 9-71 h. The average hospital stay of the HD group (10.14 ± 4.17 days) was significantly longer than that of the non-HD group (6.57 ± 1.9 days; p < 0.001). Patients in the HD group had significantly more pronounced lumen stenosis (p = 0.033) and longer plaque length (p = 0.034) than those in the non-HD group. After adjusting for age and sex, multivariate regression analysis showed that the presence of annular plaque calcification was an independent predictor of HD (odds ratio: 7.68, 95% confidence interval: 1.46-40.37, p = 0.016). CONCLUSIONS: The occurrence of annular plaque calcification in the carotid sinus was an independent risk factor for perioperative HD in CAS. Preoperative carotid CTA assists with the early identification of high-risk patients who may develop HD.

RESUMO

OBJECTIVE: The long-term outcomes of juvenile dermatomyositis (JDM) are more favorable in recent years. However, calcinosis is still among the complications that can cause serious functional impairment. Little is known about the pathogenesis and risk factors of calcinosis. The aim of this study is to determine risk factors for the development of calcinosis in JDM. METHODS: This was a single-center, retrospective cohort study. All patients were diagnosed and followed at the multidisciplinary JDM clinic of The Hospital for Sick Children, from January 1, 1989, until May 31, 2018. To investigate predictors of incident calcinosis, Cox regression analysis was performed. RESULTS: A total of 172 patients met inclusion criteria, with a median age at diagnosis of 7.7 years (IQR 4.9-12.1), and a median follow-up of 8.5 years (IQR 3.4-12.6, range 0.1-28.3). The only risk factor significantly associated with the development of calcinosis in the univariate analysis was nailfold abnormality at baseline (hazard ratio [HR] 4.86, P = 0.03). In multivariable analysis, including nailfold abnormality, age of diagnosis, sex, and duration from onset to diagnosis, the only statistically significant risk factor for calcinosis was the presence of nailfold abnormalities (HR 4.98, P = 0.03). Further, calcinosis was significantly increased in patients with a chronic course (chi-square 25.8, P < 0.001). CONCLUSION: The presence of abnormal nailfold capillary changes at baseline is predictive for the development of calcinosis in children with idiopathic inflammatory myopathies.

RESUMO

Pericatheter thrombus calcification is a complication that arises due to central venous catheter insertion and is particularly rare in peripherally inserted central catheters (PICCs). In this case report, we reviewed the clinical course of two neonates experiencing thrombus calcification. The first case involved a male neonate weighing 445 g. His PICC dwelt in the superior vena cava for over 49 days. Although a radiograph after removal did not show any silhouette, subsequent radiographs and CT depicted a catheter-like outline. Percutaneous intravascular retrieval was performed to salvage the object. Pathological examination revealed it to be a calcified cast. The calcified thrombosis was successfully dissolved with 6 months of warfarin therapy. The second case involved a male neonate weighing 534 g. After PICC removal, a catheter-like structure was shown on ultrasonograms. It was determined that invasive procedures were unnecessary for diagnosing the calcified thrombosis based on experience with the first case.

RESUMO

Calcinosis, insoluble calcium compounds deposited in skin and other tissues, is a crippling sequela of dermatomyositis. Prolonged disease associated with ongoing inflammation, ischemia, repetitive trauma, and certain autoantibodies are associated with calcinosis. Herein, we describe potential pathogenic mechanisms including the role of mitochondrial calcification. There are no widely effective treatments for calcinosis. We review available pharmacologic therapies for calcinosis including those targeting calcium and phosphorus metabolism; immunosuppressive/anti-inflammatory therapies; and vasodilators. Mounting evidence supports the use of various formulations of sodium thiosulfate in the treatment of calcinosis. Although the early institution of aggressive immunosuppression may prevent calcinosis in juvenile dermatomyositis, only limited data support improvement once it has developed. Minocycline can be useful particularly for lesions associated with surrounding inflammation. Powerful vasodilators, such as prostacyclin analogs, may have promise in the treatment of calcinosis, but further studies are necessary. Surgical removal of lesions when amenable is our treatment of choice.

RESUMO

INTRODUCTION: Arterial calcification is an integral component of active atherosclerosis and is an independent risk factor for cardiovascular disease. Atherosclerosis is a systemic, life-threating disease that may occur at different sites and in various clinical presentations. Intracranial and valvular calcifications are common among dialysis patients and have been associated with poor cardiovascular outcomes. The aim of this study was to assess the clinical impact of valvular and intracranial arterial calcifications on mortality among chronic hemodialysis patients. METHODS: A blinded neuroradiologist graded intracranial calcifications (ICC) of all hemodialysis patients who underwent brain computerized tomography (CT) from 2015 to 2017 in our institution. Valvular calcifications were assessed by echocardiography. Only hemodialysis patients with available echocardiography and brain CT were included. FINDINGS: This study included 119 patients (mean age 70.6 ± 12.6 years, 57.1% men, and mean dialysis vintage 25.8 ± 42.6 months). Among the cohort, 19 (16%) had no cardiac or brain calcifications and 65 (54.6%) had both valvular and intracranial calcifications. Considering the patients with no calcification as the reference group yielded adjusted odds ratios for all-cause mortality of 3.68 (95%CI 1.55-8.75) among patients with any brain calcifications, p = 0.002. While valvular calcifications alone did not increase the 1-year mortality rate, ICC was the most important predictor of all-cause 1-year mortality in the study cohort. DISCUSSION: We found an independent association between ICC and the risk of death among hemodialysis patients. Assessing ICC may contribute to the risk stratification of hemodialysis patients. These calcifications are no less important than valvular calcifications.

RESUMO

Background Lipoprotein(a) (Lp(a)) is a potent causal risk factor for cardiovascular events and mortality. However, its relationship with subclinical atherosclerosis, as defined by arterial calcification, remains unclear. This study uses the ARIC (Atherosclerosis Risk in Communities Study) to evaluate the relationship between Lp(a) in middle age and measures of vascular and valvular calcification in older age. Methods and Results Lp(a) was measured at ARIC visit 4 (1996-1998), and coronary artery calcium (CAC), together with extracoronary calcification (including aortic valve calcium, aortic valve ring calcium, mitral valve calcification, and thoracic aortic calcification), was measured at visit 7 (2018-2019). Lp(a) was defined as elevated if >50 mg/dL and CAC/extracoronary calcification were defined as elevated if >100. Logistic and linear regression models were used to evaluate the association between Lp(a) and CAC/extracoronary calcification, with further stratification by race. The mean age of participants at visit 4 was 59.2 (SD 4.3) years, with 62.2% women. In multivariable adjusted analyses, elevated Lp(a) was associated with higher odds of elevated aortic valve calcium (adjusted odds ratio [aOR], 1.82; 95% CI, 1.34-2.47), CAC (aOR, 1.40; 95% CI, 1.08-1.81), aortic valve ring calcium (aOR, 1.36; 95% CI, 1.07-1.73), mitral valve calcification (aOR, 1.37; 95% CI, 1.06-1.78), and thoracic aortic calcification (aOR, 1.36; 95% CI, 1.05-1.77). Similar results were obtained when Lp(a) and CAC/extracoronary calcification were examined on continuous logarithmic scales. There was no significant difference in the association between Lp(a) and each measure of calcification by race or sex. Conclusions Elevated Lp(a) at middle age is significantly associated with vascular and valvular calcification in older age, represented by elevated CAC, aortic valve calcium, aortic valve ring calcium, mitral valve calcification, thoracic aortic calcification. Our findings encourage assessing Lp(a) levels in individuals with increased cardiovascular disease risk, with subsequent comprehensive vascular and valvular assessment where elevated.

RESUMO

Dextranomer/hyaluronic acid (Deflux) has been widely used in the treatment of vesicoureteral reflux in the pediatric population. It has demonstrated acceptable early efficacy with minimal morbidity. Early complications from Deflux have been reported to occur in approximately 1% of cases. However, late complications from Deflux use, including calcification and delayed ureteral obstruction, are less well understood. We present the case of an asymptomatic 11 year old girl with severe ipsilateral hydroureteronephrosis, identified nearly 8 years after treatment. This case details a rare instance of loss of renal function after Deflux use in a patient with no apparent risk factors.

RESUMO

Mitral annular calcification (MAC) complicates the management of mitral valve (MV) disease, regardless of its etiology. Strategies to address MV surgery in MAC include two main options with their own pros and cons; respect and resect strategy. Here, we present a case of minimally-invasive MV repair with partial annuloplasty in the management of noncircumferential MAC with respect to strategy. This technique may be an alternative option for rescuing high-risk patients without extensive decalcification.

RESUMO

In our current practice, the use of JJ probes has become extremely frequent. However, incrustation and fragmentation of JJ leads are still relatively common and sometimes complicate removal. A 61-year-old woman with a history of hysterectomy ten years ago, she had a double J endo-ureteral stent for preoperative identification of the right ureter. The patient has forgotten the double J stent. She currently has right lower back pain and urinary tract symptoms of urinary. Uroscan revealed a very important right hydronephrosis, a fully calcified right double J stent with a calcification of 6 cm at the level of the lower loop. She had, at first, a cystotomy allowing the extraction of the lower part of the calcified stent and secondly a pyelotomy to extract the rest of the double J stent. The operative follow-up was simple. The use of a double J probe to divert the urinary tract is an effective and generally well tolerated technique. Regular monitoring prevents complications.
